本文提出了一种新的方法来反演单分子高次谐波的角分布。这种技术使用的迭代过程仅基于时间和角度依赖的谐波信号的实验结果，并没有假设分子轨道的实际形状。该方法可以同时计算出目标气体中分子的轴向分布。的角度依赖的信号检索为一个单一的N2和O2分子被证明反映最高占据的分子轨道，排除由于不完美的对齐的模糊性。
We present a novel method to retrieve angular distributions of high-order harmonic generation from a single molecule. This technique uses an iterative procedure based only on experimental results of time and angle-dependent harmonic signals, and no actual shape of molecular orbital is assumed. The molecular axis distribution in a target gas can simultaneously be deduced in this procedure. The angle-dependent signal retrieved for a single N2 and O2 molecule is demonstrated to reflect the highest occupied molecular orbital, excluding the ambiguity due to the imperfect alignment.
